1Effect of vegetation of transgenic Bt rice lines and their straw amendment on soil enzymes, respiration, functional diversity and community structure of soil microorganisms under field conditions显示文摘With the development of transgenic crops, there is an increasing concern about the possible adverse effects of their vegetation and residues on soil environmental quality. This study was carried out to evaluate the possible effects of the vegetation of transgenic Bt rice lines Huachi B6 (HC) and TT51 (TT) followed by the return of their straw to the soil on soil enzymes (catalase, urease, neutral phosphatase and invertase), anaerobic respiration activity, microbial utilization of carbon substrates and community structure, under field conditions. The results indicated that the vegetation of the two transgenic rice lines (HC and TT) and return of their straw had few adverse effects on soil enzymes and anaerobic respiration activity compared to their parent and distant parent, although some transient differences were observed. The vegetation and subsequent straw amendment of Bt rice HC and TT did not appear to have a harmful effect on the richness, evenness and community structure of soil microorganisms. No different pattern of impact due to plant species was found between HC and TT. It could be concluded that the vegetation of transgenic Bt rice lines and the return of their straw as organic fertilizer may not alter soil microbe-mediated functions.Hua Fang Bin Dong Hu Yan Feifan Wang Baichuan Wang Yunlong Yu 2012Journal of Environmental Sciences2012,24,7:21
2Disease profile and plasma neutralizing activity of postvaccination Omicron BA.1 infection in Tianjin,China:a retrospective study显示文摘Dear Editor,SARS-CoV-2 Omicron variant BA.1 first emerged on the Chinese mainland on January 8,2022,in Tianjin and caused a large wave of infections.1 Four rounds of mass testing of its~14 million residents were launched on January 9,12,15,and 20,respectively.As of February 7,2022,a total of 430 individuals were tested positive for Omicron BA.1,with no new infections detected for the following 16 days.In the Chinese mainland,the most delivered vaccines are inactivated vaccines.As of January 8,2022,up to 93.2%of Tianjin’s residents had been vaccinated with at least one dose.2 We investigated the protection conferred by vaccination against Omicron BA.1 by examining the breakthrough infections among vaccinees as compared with unvaccinated cases.Our study population comprised all 430 cases during the outbreak of Omicron BA.1 in Tianjin.Hong Zheng Yunlong Cao Xiaosu Chen Fengmei Wang Ye Hu Weiliang Song Yangyang Chai Qingqing Gu Yansong Shi Yingmei Feng Shuxun Liu Yan Xie Xiaoliang Sunney Xie Wentao Jiang Zhongyang Shen 2022Cell Research2022,32,8:12
3Inhibition of Rac1-dependent forgetting alleviates memory deficits in animal models of Alzheimer's disease显示文摘Accelerated forgetting has been identified as a feature of Alzheimer's disease(AD),but the therapeutic efficacy of the manipulation of biological mechanisms of forgetting has not been assessed in AD animal models.Ras-re-lated C3 botulinum toxin substrate 1(Rac1),a small GTPase,has been shown to regulate active forgetting in Drosophila and mice?Here,we showed that Rac1 activity is aberrantly elevated in the hippocampal tissues of AD patients and AD animal models.Moreover,amyloid-beta 42 could induce Rac1 activation in cultured cells.The elevation of Rac1 activity not only accelerated 6-hour spatial memory decay in 3-month-old APP/PS1 mice,but also significantly contributed to severe memory loss in aged APP/PS1 mice.A similar age-dependent Rac1 activity-based memory loss was also observed in an AD fly model.Moreover,inhibition of Rac1 activity could ameliorate cognitive defects and synaptic plasticity in AD animal models.Finally,two novel compounds,identified through behavioral screening of a randomly selected pool of brain permeable small molecules for their positive effect in rescuing memory loss in both fly and mouse models,were found to be capable of inhibiting Rac1 activity.Thus,multiple lines of evidence corroborate in supporting the idea that inhibition of Rac1 activity is effective for treating AD-related memory loss.Wenjuan Wu Shuwen Du Wei Shi Yunlong Liu Ying Hu Zuolei Xie Xinsheng Yao Zhenyu Liu Weiwei Ma Lin Xu Chao Ma Yi Zhong 2019Protein & Cell2019,10,10:10

6Co-infections of SARS-CoV-2 with multiple common respiratory pathogens in infected patients显示文摘Dear Editor,In late December 2019,an outbreak of severe pneumonia caused by an unknown etiological agent was initially reported in Wuhan,China,and then quickly spread throughout China and even abroad(Zhu et al.,2020).Swift control measures and etiological investigations were conducted by the Chinese government,physicians and researchers,and by using high throughput sequencing and virological testing,the mysterious pneumonia pathogen was shown to be a novel coronavirus(SARS-CoV-2)capable of person-to-person transmission(Zhu et al.,2020).Coronaviruses are a group of non-segmented,enveloped and positive-sense RNA viruses that belong to the subfamily of Coronavirinae in the family of Coronavirdiae and order of Nidovirales.Dachuan Lin Lei Liu Mingxia Zhang Yunlong Hu Qianting Yang Jiubiao Guo Yongchao Guo Youchao Dai Yuzhong Xu Yi Cai Xinchun Chen Zheng Zhang Kaisong Huang 2020Science China(Life Sciences)2020,63,4:6
7Progress and challenges in blocked impurity band infrared detectors for space-based astronomy显示文摘Astronomical detection at infrared wavelengths is crucial in astrophysics due to the critical information in this wavelength range.Blocked impurity band(BIB) infrared detectors are desirable for space-based astronomical observation due to their broad response range, low dark currents, high quantum efficiencies, and excellent radiation resistance. In this review, typical BIB device structures and device physics development are first introduced. Subsequently, we discuss progress in Si-based BIB detectors with different doping types and emphasize their applications in space-based infrared detection. Additionally, we discuss recent efforts on pixel performance optimization, response extension, and higher operating temperature devices. Finally,we conclude by proposing the challenges and perspectives of BIB detectors with improved detection performances.Yunlong Xiao He Zhu Ke Deng Peng Wang Qing Li Ting He Tao Zhang Jinshui Miao Ning Li Wei Lu Ning Dai Weida Hu 2022Science China(Physics,Mechanics & Astronomy)2022,65,8:4

9Parallel Spectral Clustering Based on MapReduce显示文摘Clustering is one of the most widely used techniques for exploratory data analysis.Spectral clustering algorithm,a popular modern clustering algorithm,has been shown to be more effective in detecting clusters than many traditional algorithms.It has applications ranging from computer vision and information retrieval to social science and biology.With the size of databases soaring,clustering algorithms have scaling computational time and memory use.In this paper,we propose a parallel spectral clustering implementation based on MapReduce.Both the computation and data storage are distributed,which solves the scalability problems for most existing algorithms.We empirically analyze the proposed implementation on both benchmark networks and a real social network dataset of about two million vertices and two billion edges crawled from Sina Weibo.It is shown that the proposed implementation scales well,speeds up the clustering without sacrificing quality,and processes massive datasets efficiently on commodity machine clusters.Qiwei Zhong Yunlong Lin Junyang Zou Kuangyan Zhu Qiao Wang Lei Hu 2013ZTE Communications2013,11,2:3
10Pressure induced convergence of conduction bands in Al doped Mg_(2)Si: Experiment and theory显示文摘High-pressure and high-temperature(HPHT)synthesis provides an effective way to tune the band structure of materials and improve their electronic properties.To investigate the influence of synthesis pressure on electronic properties,Mg_(1.97)Al_(0.03)Si samples were synthesized using the HPHT method.The maximum effective mass 0.92me is obtained for the sample prepared with the synthesis pressure of 3 GPa,leading to the biggest Seebeck coefficient201.3 mV/K at room temperature.Meanwhile,the 3 GPa sample obtains the higher electron carrier concentration and electrical conductivity,resulting in nearly overall enhancement of power factor.The Density Functional Theory(DFT)calculations evidences that the Conduction Bands Minimum(CBM)can be tuned effectively by applied pressure and the convergence of the CBM leads to a larger effective mass of DOS,which are beneficial to the enhancement of power factors.These results indicate that high-pressure is a powerful tool to tune Mg_(1.97)Al_(0.03)Si band structures.Jialiang Li Xiaolian Zhang Bo Duan Yunlong Cui Houjiang Yang Hongtao Wang Junchao Li Xiaojun Hu Gang Chen Pengcheng Zhai 2019Journal of Materiomics2019,5,1:2

13Synthesis of Low-cost LiFePO_4 from Li_2CO_3 by a Novel Hydrothermal Method and Investigation on the Reaction Mechanism显示文摘Phspho-olivine Li Fe PO4 was synthesized from the relatively insoluble lithium source Li2CO3, proper iron and phosphorus sources(n(Li):n(Fe):n(P)=1:1:1) by a novel hydrothermal method. Afterwards, the optimal sample was mixed with glucose and two-step calcinated(500 ℃ and 750 ℃) under high-purity N2 to obtain the Li Fe PO4/C composite. The resultant samples were characterized by X-ray diffraction(XRD), atomic absorption spectrometry(AAS), scanning electron microscops(SEM), transmission electron microscopy(TEM), energy dispersive spectrometry(EDS), elementary analysis(EA) and electrochemical tests. The results show that the optimal reaction condition is to set the reactant concentration at 0.5 mol·L-1, the reaction temperature at 180 ℃ for 16 h duration. During the reaction course, an intermediate product NH4 Fe PO4·H2O was first synthesized, and then it reacted with Li+ to form Li Fe PO4. The optimized Li Fe PO4 sample with an average particle size(300 to 500 nm) and regular morphology exhibits a relatively high discharge capacity of 84.95 m Ah· g-1 at the first charge-discharge cycle(0.1C, 1C=170 m A·g-1). Moreover, the prepared Li Fe PO4/C composite shows a high discharge capacity of 154.3 m Ah·g-1 at 0.1C and 128.2 m Ah·g-1 even at 5C. Besides it has good reversibility and stability in CV test.李向锋 HU Yunlong LIU Fang 张昭 2015Journal of Wuhan University of Technology(Materials Science)2015,30,2:2
